Solution

1. Preparation

Gather necessary tools: Multimeter, fuse puller, socket set, and screwdrivers.
Disconnect the battery to ensure safety.

2. Check and Replace Fuses

Locate the fuse box under the dashboard or in the engine compartment.
Use the fuse puller to remove the power window fuse.
Inspect the fuse for continuity; replace if blown with the same amperage rating.
Reconnect the battery and test the power windows.

3. Inspect and Test the Power Window Switch

Remove the door panel using screwdrivers and trim tools.
Disconnect the power window switch connector.
Use a multimeter to test for continuity between the terminals of the switch when pressed.
If the switch is faulty, replace it with a new one.

4. Test the Window Motors

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Use jumper wires to connect the motor directly to the battery; observe if it operates.
If the motor does not work, replace it.

5. Check Wiring and Connections

Inspect the wiring harness from the power window switch to the motor for frays or breaks.
Ensure all connectors are securely connected and free from corrosion.
Repair or replace any damaged wiring as necessary.
